It's a fresh install, I imported as you said. Actually importing this model was the first thing I did after installing and updating. There were no errors or anything when importing or rendering and none of my other helis act weird, not sure what's up.

I'll try to remember to check next time it does it. Flew it pretty hard today and no issues at all, though my roommate said the same thing I explained had happened to him when he was flying earlier. Seems to come and go, so strange.

I had the tail freak out once or twice on me today as well, it's odd how inconsistent the issues are.

EDIT: Just had a thought, roommate said he had to switch the sim setting from Intermediate to Advanced after the fresh install. Maybe in the Intermediate setting it increases headspeed if it thinks the blades are about to bog and it was overspeeding as soon as the load reduced, or it was just over compensating? Just baseless conjecture, I have no idea what those settings really affect.

I love the overall feel of this model but I'm having some weird issues with it, running 4.5.

The tail acts very strange, it's both twitchy and always drifting. Even weirder is that it started folding up the blades and falling out of the sky when I piro flip it, I can't figure that one out at all and I'm pretty sure it wasn't doing that at first.

If anyone can offer suggestions to straighten these issues out I'd be very appreciative. I just got a 500ESP 3gx and this model feels fairly similar to it. Definitely close enough for good practice

I am having this same problem ever since i've gotten realflight. Already tried to go through all of the heli settings trying to get that tai to hold still, but it still fails on me way to much.
